Homework Statement
I have a cube with four faces parallel to the field and two perpendicular.
The field is non uniform, given by E = 3 + 2x^2 in the +x direction.
The Attempt at a Solution
So I get [tex]\phi = \int \vec{E} \cdot d\vec{A} = \int EdA = A \int E = A \int (3+2x^2)[/tex]
But how do I evaluate this with no dx?
